Can SIMBA be used in Thailand?
Yes, SIMBA roaming works in Thailand across all major plan tiers. Thailand is included in SIMBA’s Main Data zone, as well as its APAC Roaming and Group A international roaming coverage.
Depending on your plan, SIMBA may treat data usage in Thailand as:
- Part of your Main Data zone (with no extra roaming charges)
- Covered under the APAC Roaming zone, for use across select regional destinations
- Or eligible through a Group A roaming add-on, which provides a fixed data allowance for use across 60+ countries
Your data access in Thailand will follow the conditions of your active plan, so checking your roaming entitlement before departure is key.

In this section, you’ll find a full breakdown of available SIMBA Thailand roaming, including prices, data limits, and what happens if you exceed your allowance.
SIMBA prepaid roaming for Thailand
SIMBA’s SuperRoam prepaid plans include roaming data for Thailand, which is covered under both Group A (60+ countries) and APAC roaming zones.
Except for SuperRoam 10, all prepaid plans also include Thailand in their main local data coverage, meaning you can use your regular data allowance while in Thailand.
Once your local data runs out, usage will first draw from your APAC allowance, then from your global roaming quota.
